Abstract: PURPOSE:To reduce the evaporating amount of the metal composing an electrode, suppress fouling a glass bulb and thereby lessen the decrease of the light flux by having the discharge electrode composed of the basic metal coated with the mixture of specific amount of LaB6 and BaAl2O3. CONSTITUTION:A discharge electrode 2 has a top-covered tube 8 which provides a through-hole 7 at the top part of a basic metal with high melting point such as molybdenum or the like so as to allow electron emission also from the inner face of the basic metal.

Abstract: PURPOSE:To contrive the high integration of an integrated circuit and the speed- up of a transistor as a discrete element by a method wherein a base and a collector are formed in a structure of isolation by an insulator thin film except for the region immediately under an emitter, and the base and emitter parts are formed in a crystalline film isolated from a substrate. CONSTITUTION:P implantation of 1X10<16>/cm<-3> is performed into the P type Si substrate 41, and annealed resulting in the formation of an N<+> region 42 serving as the collector region. An oxide film 43 is formed in the process of activation of implanted impurity, whereon aperture parts 44 and 44' are provided respectively at a base-collector junction part and a collector electrode forming part by lithography. Fusion is performed to approx. the half of the depth of the polycrystalline Si and selectively epitaxial-grown N<-> region 44, and then the fused part changes into a single crystal at the time of solidification with the remnant part as a seed. Next, the recrystallized layer 47 of an unnecessary part is removed, and the As of 1X10<16>cm<-2> is ion-implanted into a part 48 serving as the emitter and the aperture part 46 for a collector electrode. An emitter electrode 40, a base electrode 40', and a collector electrode 40'' are formed by patterning, and accordingly a transistor is formed.

Title: Adpcm codec
Inventor: FUKAZAWA ATSUSHI
IPC: H03M7/36
Filed: 1986-03-31
Abstract: PURPOSE:To decrease the deterioration in a characteristic even when an ADPCM CODEC is used to a system generated with a transmission line bit error by calculating a control signal used for the control of an amplitude control coefficient by the use of a signal at the outside of a loop including the amplitude control coefficient. CONSTITUTION:Adaptive zero forecast filters 121,122, adaptive pole forecast filters 123,124 and fixed pole forecast filters 125,126 as adaptive forecast filters are connected in cascade both for coder and decoder sides. Amplitude control coefficients gap(k), gfp(k) are controlled by signals Ca(k),Cf(k) generated by control signal generating circuits 101-104. Since an input signal to the control signal generating circuits 101-l04 uses reproduction residual signals-e2(k),-e1(k), the amplitude control coefficients gap(k),gfp(k) are controlled without using a signal in a loop including the amplitude control coefficients gap(k),gfp(k).

IPC: G01N29/26
Filed: 1978-06-13
Abstract: PURPOSE:To improve the resolution of an ultrasonic oscillator by overlapping the circle motions of larger and smaller diameters upon the linear motions in the radial direction of the larger circle motion. CONSTITUTION:An ultrasonic oscillator 26 performs a circle motion of a larger diameter X, in case it does not drive a first rotor 5 as well as a motor 2, through an upper disc 13, a tie rod 15, a lower disc 14 and a screw gears 21 and 23 by the rotations of a second rotor 12 relative to a second stator 33. In case the first and second rotors 5 and 12 are not driven, the oscillator 26 performs a circle motion of a smaller diameter Y through a drive shaft 3, a connecting shaft 31 and a crank shaft 27 by the rotations of the motor 2. In case, moreover, the motor 2 and the rotor 12 are not driven, the oscillator 26 is reciprocally moved in the diametrical direction of a frame 1 within a range of a distance L through the gears 21 and 23 and a sleeve 25 by the rotations of the rotor 5 relative to the first stator 32. As a result, with the simultaneous drives of those, the resolution by the oscillator can be remarkably improved by the trocoidal motions performed.

CONSTITUTION:A cured film is formed on the title composite membrane by using a coating substance which is liquid in a range within 5-35 deg.C. After curing this coating substance by a means such as heating or chemical reaction using a catalyst, it must be solidified. Further as the coating substance, such a substance is preferably used that it has mechanical strength in a point of durability as a separation membrane after curing and is not easily allowed to flow out and transferred and is easily made to high polymerization or has a crosslinked structure. As such coating substance, curing type organosiloxane, curing type urethane resin and curing type epoxy resin, etc., are used. Repair of a fault is effectively performed by applying this coating substance to the permselective composite membrane and curing it.

Abstract: PURPOSE:To prevent a wedge-shaped stress concentration generated in an arm member by forming wedge parts on both end parts of the arm member, and forming taper-shaped recessed parts engaging with the wedge parts in a ring member connected to both end parts of the arm member. CONSTITUTION:In a suspension arm 10, a connecting ring member 12 is engaged with both end parts of an arm member 11, and a fiber layer 13 is formed on the outer periphery of the ring member 12. The arm member 11 is then formed into a H-shaped cross section with a vertical face 15 being held between a pair of parallel faces 14. In this case, the vertical face 15 of the arm member 11 is protected from the parallel faces 14, and both faces 15a in the direction of thickness of the vertical face 15 are tilted in an abutted manner to form a wedge part 15b. On the other hand, a taper-shaped engaging recessed part 17 conforming to the shape of the wedge part 15b is formed in the inside end of the ring member 12. The arm member 11 and the ring member 12 can thus be connected to each other by engaging the wedge part 15b with the engaging recessed part 17.

Title: A/d converter
Inventor: TAGUCHI AKIYOSHI
IPC: H03M1/10
Filed: 1989-03-24
Abstract: PURPOSE:To eliminate the dangerous factors which cause the system malfunctions by preparing a function which always performs the self-diagnosis of accuracy of a comparator. CONSTITUTION:The 1/2 reference power voltage VREF is inputted as an analog input through a 1/2 VREF level line 8 for check of the accuracy of a comparator 2. In this case, the input of an external signal is inhibited to an input port 4 via an input switching signal line 9. If the accuracy of the comparator 2 is deteriorated by some reason, the result of A/D conversion is equal to [0101] B to the 1/2 VREF and latched by a register 5. At the same time, the abnormal state of the comparator 2 is informed to an A/D conversion part 1 and other circuits. Thus the self-diagnosis is always performed for the accuracy of the comparator 2 and therefore the deterioration of accuracy is immediately detected for preparation of a necessary measure. As a result, the system malfunctions can be prevented.

Abstract: PURPOSE:To prevent a BaSnO3.3H2O bulky crystal from affecting an exhaust gas sensor by specifying the size and content of a crystallite in BaSnO3.3H2O when the crystal of BaSnO3.3H2O is decomposed to BaSnO3. CONSTITUTION:Those using a starting material containing a large quantity of BaSnO3.3H2O bulky crystals are, for example, high in a resistance value in the rich atmosphere and at a low temperature and its tolerance to a sensor temperature is narrowed. It is hard to precipitate BaSnO3.3H2O containing no bulky crystals. Then, the proportion of a crystallite with the shorter diameter of more than 25mum in BaSnO3.3H2O is limited to 5% or less with the number of particles as standard. The content of the bulky crystal is measured by observing the BaSnO3.3H2O crystal or skeleton particle after temporary sintering. BaSnO3.3H2O is a needle state crystal and can be a hexagonal crystal. The ratio of the longer diameter to the shorter diameter of the bulky crystal is smaller than a normal crystal. The particles after temporary sintering can be observed.
